Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expert knowledge and manual adjustment of multiple hardware pieces are used for sound equalization, then audio optimization precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple hardware components (audio interface, processor, display) into an integrated mobile device that performs sound equalization. The processor integrates equalization algorithms and controls multiple hardware pieces through a unified system, eliminating the need for separate expert-operated equipment while maintaining optimization precision.
Solution Approach 2:
The mobile device performs automatic sound equalization through integrated algorithms that analyze audio signals and adjust settings without requiring expert knowledge. The system self-calibrates by processing audio data through the audio interface and automatically applying corrections, making the complex process accessible to non-experts.
2Measurement precision
If expert knowledge and manual testing are used for sound equalization, then audio optimization precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual mechanical adjustment of equalization settings with automated digital signal processing. The processor executes equalization algorithms that automatically analyze and correct frequency responses, substituting expert manual operations with computational methods that maintain accuracy while improving ease of use.
Solution Approach 2:
The mobile device acts as an intermediary between the audio system and the user, providing a user-friendly interface that abstracts complex equalization processes. The display and interface present simplified controls and visualizations, allowing non-experts to access and adjust equalization settings without needing to understand the underlying technical complexity.
3Measurement precision
If multiple hardware pieces are used for sound equalization, then audio optimization precision is improved, but ease of operation deteriorates
Solution Approach 1:
The mobile device serves multiple functions within a single unit: it acts as an audio interface, processor, display, and control system for sound equalization. This multi-functional integration maintains the measurement accuracy of specialized equipment while eliminating the need to operate multiple separate hardware pieces, thereby simplifying user operations.
